Double-lumen endobronchial tube

Abstract

The invention discloses a double-lumen endobronchial tube. The double-lumen endobronchial tube comprises a tube body to be inserted into a patient's bronchus, inflation valves, and an air bag; an auxiliary vent pipe and a main vent pipe are arranged in the tube of the tube body in an inserted way; the auxiliary vent pipe is seized inside the main vent pipe; a rubber snap ring is arranged outside one end of the auxiliary vent pipe; the inflation valves comprise a tube inflation valve and a vent pipe inflation valve; the tube inflation valve is arranged on the tube body; the vent pipe inflationvalve is arranged on the auxiliary vent pipe; the auxiliary vent pipe is inserted into the main vent pipe; and the auxiliary vent pipe and the main vent pipe themselves have certain radian, so that the auxiliary vent pipe and the main vent pipe can easily enter bilateral bronchi after extending into the interior of the tube body so as to facilitate tube insertion. Compared with the prior art, operation is carried out by adopting the auxiliary vent pipe with small diameter in the scheme, so that tube insertion is facilitated; and moreover, the auxiliary vent pipe with small diameter itself hasa certain moving radian, so that the auxiliary vent pipe can easily extend into the interior of the left bronchus so as to facilitate treatment.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a double-lumen bronchial catheter. Background technique [0002] Endotracheal intubation technology is widely used in the rescue of anesthetized or critically ill patients. It can quickly establish an artificial airway to ensure the oxygen required by the patient's metabolism. Especially in thoracic surgery, most patients need to isolate the bronchial airways of the left and right lungs through a double-lumen bronchial catheter to achieve selective one-lung ventilation. Usually, the left bronchial angle of the body is compared to the right The angle of inclination of the bronchus is too large, and the diameter of the auxiliary ventilator in the prior art is relatively thick, so it is very difficult to place the tube. Forcible intubation will cause local injuries to the patient, and at the same time delay the time of treating the patient, or use a bronchoscope For treatme...

Problems solved by technology

Especially in thoracic surgery, most patients need to isolate the bronchial airways of the left and right lungs through a double-lumen bronchial catheter to achieve selective one-lung ventilation. Usually, the left bronchial angle of the body is compared to the right The angle of inclination of the bronchus is too large, and the diameter of the auxiliary ventilator in the prior art is relatively thick, so it is very difficult to place the tube. Forcible intubation will cause local injuries to the patient, and at the same time delay the time of treating the patient, or use a bronchoscope For treatment, however, the bronchoscope is expensive and difficult to operate, so we provide a double-lumen bronchial catheter to solve the problems raised in the above-mentioned background technology
